Cylinder Block, Liners, Pistons, and Rods
INSTALL LINER SHIMS--IF REQUIRED
If the liner flange thickness is within specification, but
recorded standout was no more than 0.08 mm (0.003 in.)
BELOW top deck of block, install liner shims on bottom of
liner flange.
The liner shim is 0.05 mm (0.002 in.) thick. A maximum of
two liner shims may be used per cylinder, as required.
Shims have tangs in the I.D. to help hold them in place
against bottom of liner flange during liner installation.
1. Make sure counterbore in block is clean and free of
burrs. Install liner(s), and shim(s), in block bore without
O-rings. Secure liners with cap screws and washers as
done previously. Tighten cap screws to 68 Nm (50
lb-ft).
Liner standout MUST NOT exceed 0.102 mm
(0.004 in.) after shim installation.
2. Measure liner standout again at 1, 5, 7, and 11 O'clock
positions. Record measurements.
If standout is still not within specification, remove liner
and determine cause.
If standout is within specification, proceed to next step.
